WebWhich section of a research article is most likely to provide suggestions for additional research? The discussion will always connect to the introduction by way of the research questions or hypotheses you posed and the literature you reviewed, but the discussion does not simply repeat or rearrange the first parts of your paper; the discussion clearly explains how your study advanced the reader's understanding of the research problem from where you left them at the end of your review of prior research. Causal inference in statistics, social, and biomedical sciences. This often applies to larger differences in p as well. Readers may take this article as an invitation to read further papers discussions differently while evaluating our claims. Making broad claims, strong statements (8), and conclusions such as more work is needed to be done should preferably be avoided (6). The distinction is profound, since a newly proposed hypothesis just makes a new claim. classifying a true depression case as non-case) or the prevalence of a binary confounder and its effects on X and Y. Thrower PA. measurement error might differ between a clinical and a general population) [5, 6]. The discussion can be closed with one or two sentences as the take-home message, viz. Analytical thinking (hypothetico-deductive reasoning) may confirm or reject the spontaneous solutions emerging from intuitive thinking (26). Oksbjerg S, Mellemkjr DL, Olsen JO, Johansen C. Depression and Cancer risk: a register-based study of patients hospitalized with affective disorders, Denmark, 19691993. Annesley, Thomas M. The Discussion Section: Your Closing Argument., Most effectively demonstrates your ability as a researcher to think critically about an issue, to develop creative solutions to problems based upon a logical synthesis of the findings, and. Metadiscourses establish logical connections between different parts of a text and are used for making the text structure and purposes more explicit (22). Consequently, reasoning on bias tends to be vague, unclear and superficial. FOIA Received 2019 Jun 16; Revised 2019 Jul 8; Accepted 2019 Jul 10. ", One of the most common mistakes that you can make when discussing the results of your study is to present a superficial interpretation of the findings that more or less re-states the results section of your paper. Of course, there are numerous relevant factors in the medical field. methods expert) and a substantive researcher should take. Avoiding discussion of unexpected results is a common pitfall in writing a discussion (2). Models, Reasoning and Inference. Detailing the writing of scientific manuscripts: 25-30 paragraphs. The sequence of this information is important; first state the answer, then the relevant results, then cite the work of others. The most important dos and donts of writing a discussion section are provided in Box 1. We illustrate this through the personal roles that a statistician (i.e. In fact, such inference requires an a-priori calculated sample-size to ensure that the type-two error probability does not exceed a pre-specified limit (typically 20% or 10%, given the other necessary assumptions, e.g. III. A poor discussion can hurt the paper (5); hence, the writing of this section needs more effort than other parts of the manuscript (7). Discussion: The heart of the paper. This section interprets the results for readers and provides the meaning and implications of the findings (2). Before Of course, bias analysis also changes point estimates (hopefully reducing bias considerably). HHS Vulnerability Disclosure, Help If this holds true for all common factors of D and LC, upward bias can be assumed. When this happens a statistician alone is limited to a studys conditions (sampled population, experimental settings etc. MH has taken the lead in writing. A result different to those of other reports, which may be due to different effects of biases across the studies (14), does not necessarily indicate that there is a mistake or error (2) and it may just need an explanation (16), e.g. The discussion section is the most important and the most creative section of your paper for telling your story (1-4). The Discussion section of an article, as the name suggests, is meant to discuss the results of the study with respect to the problem of the study. This again has to be brought up by statistical expertise. Discussion / Analysis (What it means) This section should tell you what the authors felt was significant about their results. Overall, the active voice should predominate although a few selected sentences in the passive form can be used (2, 46). The discussion section: Your closing argument. Presenting findings that have not been described in the methods or results section is a common pitfall of the discussion, which readers find perplexing (2, 7). Beyond providing the most important principles and common strategies for organizing the discussion section, we also discuss metadiscourse, scientific explanation (reasoning and contextualization), and models of scientific explanation. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Note that the order of the points is not meant to structure a discussions writing (besides 1.). Obviously, you must refer to your results when discussing them, but focus on the interpretation of those results and their significance in relation to the research problem, not the data itself. Hfler M. The Bradford Hill considerations on causality: a counterfactual perspective. The site is secure. At the end of the discussion (the last paragraph), the conclusion and take-home message are presented (2, 6) by restating the answer to the question, indicating the importance of the study, or both (12). Contexts of the study include the scientific, clinical, social, political, and epistemological arenas to which the study may contribute (7). The discussion also contains statements about the significance and/or novelty of the study, contextualized important results, related research (with both similar and opposite findings), arguments about unexpected results, strengths/weaknesses of the study, implications and future perspective/recommendations, and the take-home message (2, 6, 12). Rather than sharing a provided conclusion (or not) they could ask themselves whether a discussion enables them to clearly specify why they share it (or not). Federal government websites often end in .gov or .mil. to be reported in the methods and results section and addressing sources of potential bias, limitations and considering other relevant evidence in the discussion [8, 9]. Greenland S. Multiple-Bias modelling for analysis of observational data. Increasing disparities between resource inputs and outcomes, as measured by certain health deliverables, in biomedical research. de investigacion social. Therefore, unlike deduction, induction is knowledge-rich, as deduction depends on premises, not other background knowledge. sharing sensitive information, make sure youre on a federal Docherty M. The case for structuring the discussion of scientific papers. Exploiting 2-dimensionality in the online world. Practicing medicine in Plato's Cave. Scientific explanation is most convincing when the underlying causes of a phenomenon are provided. One can use both approaches in the conclusion section (12). Thus, you need to Be certain that you clearly identify your comments as speculation or as a suggestion for where further research is needed. Federal government websites often end in .gov or .mil. He or she could infer upward bias instead if well-informed on the line of argument. Analyzing vs. Summarizing. If the substantive investigator understands the processes of selection, measurement and confounding only poorly, such strict analysis numerically reveals that little to nothing is known on the effect of X on Y, no matter how large an observed association and a sample (providing small random error) may be [5, 6, 23]). In this section, present tense is used for presenting general knowledge and universally accepted facts (3, 37). The discussion section forms an integral part in the writing process of a research article (RA). The Technicality of the Research. Compared to other sections in a research paper, the discussion was about the same length as either the methods or the results, and double the length of the introduction. This assumes that all parameter values were equally likely (uniformly distributed, strictly speaking) before analyzing the data [5, 6, 20]. In: Ahrens W, Pigeot I, editors. In analogy, this section acts as the global positioning system (GPS) (7, 15) to show the reader how far we moved with this study on the science road (7). The proposals made in this article could help shifting scientific debates to where they belong. Usually articles end with statements that only go little further than the always true but never informative statement more research is needed. Extrapolating the results to another population than the source population requires what is called external validity, transportability or the absence of selection bias [18, 19]. In the above example, a substantive researcher might want to conclude that D and LC are associated in a general population instead of just inferring to patients in primary care settings (a.). The discussion section, the most creative and important part of a paper, is expected to inform readers how far we have moved on after this study on the science road. For instance, in a large sample, a Pearson correlation between two dimensional variables could equal 0.1 only but with a p-value <.001. The recommendations are intended to be suggestions rather than rules. MH and RM had the initial idea on the article. Consider conclusion a. and suppose that, instead of representative sampling in a general population (e.g. This is also addressed by Bayesian statistics that allows calculating what frequentist p-values are often misinterpreted to be: the probability that the alternative (or null) hypothesis is true [17]. IV. Fingerhut A, Sarr MG. Inclusion in an NLM database does not imply endorsement of, or agreement with, Abstract An abstract is included in most academic journal articles. In the discussion, ambiguous points should be highlighted and specific suggestions demonstrated by the completed project for further research be provided (3, 4). Braaten M, Windschitl M. Working toward a stronger conceptualization of scientific explanation for science education. (Fig.33). Masic I. Instead of accepting the variety of possible assumptions, it makes the absurd assumption of no bias with probability of one. Provide a future perspective on the work. If one is only interested in association, confounding is irrelevant. In this case, the wording there is no evidence for an association is adequate because it does not claim that there is no association. goes from narrow to broad and ends in the bigger picture (Figure 2). If a limitation is applicable to the method chosen to gather information, then describe in detail the problems you encountered and why. Although such an analysis is complicated, itself very sensitive to how it is conducted [5, 6] and rarely done, the Bayesian thinking behind it forces researchers to better understand the processes behind the data. Authors are advised to avoid beginning the discussion with a summary of the results (12); such summaries are only appropriate for studies with a huge amount of results; for studies with short discussions, it is frustrating for readers to have to read the results again (7). An introduction to appraisal: assessing the evidence. Alpert JS. Modified from the Department of Sociology, SUNY Brockport: https://www.brockport.edu/academics/sociology/journal.html Speculations are similar to implications but are more tentative; however, reasonable speculations for suggesting a relationship between ideas are useful and need to be included in the discussion section (12). The discussion section should relate your results to those found in other studies, particularly if questions raised from prior studies served as the motivation for your research. Offers detailed guidance on how to develop, organize, and write a college-level research paper in the social and behavioral sciences. Careers, Unable to load your collection due to an error. Discussion -The discussion section contains the interpretations and implications of the study. If a study that you cited does not support your findings, don't ignore it--clearly explain why your research findings differ from theirs. Answers are not the same as the results but are a generalization of the results and should be limited to the study population (12). 2013;13. For example, D and LC might share several causes such as stressful life events or socioeconomic status. Some description of performance status was added in the Discussion section.Once again, thank you very much for your comments and suggestions. ), because he or she is unaware of the conditions generalizability. Bibliography of guides to scientific writing and presenting. For instance, bias might act differently across the dose of exposure (e.g. This model uses deductive reasoning for explaining that an event is expected to be the logical result of a law; one example is Boyles law for explaining the relationship between volume and pressure of a gas and the other is the negative feedback regulation for secretion of most hormones in endocrinology. The order of the topics in the middle section is dictated by the science or they are organized from the most to the least important related to the answer (12). Identify the individuals for whom you are writing your research article. The discussion section can be written in 3 parts: an introductory paragraph, intermediate paragraphs and a conclusion paragraph. This can be followed by any recommendations for further research. onset of depression). If they are not consistent, the question arises why inconsistency occurs maybe because of bias acting differently across studies [57]. Textual functions of metadiscourse include guiding the reader through the text, signaling the sequence, providing connections between ideas, and organizing discourse through topic shifts (23, 24). primary outcome(s), is presented (2, 7), trying to answer the question(s) and supporting your answers with results (12). d. Identify the individuals who are likely cited in your paper. You should frame your suggestions by linking the need for further research to the limitations of your study [e.g., in future studies, the survey instrument should include more questions that ask"] or linking to critical issues revealed from the data that were not considered initially in your research. RM has refined the paragraphs on statistical inference. PLoS Biol. NOTE: Besides the literature review section, the preponderance of references to sources is usually found in the discussion section. Remember that the data are the data: nothing more, nothing less. Also do not repeat your results, this is a discussion. The environment and disease: Association or causation? They should, however, be aware that consistency between their results and data available may only be due to shared biases (14). Yet very different mechanisms could have produced such an association [7], and assumptions on these lead to the following fundamentally different conclusions (Fig. Goals:Present principles, relationships and generalizations shown by the resultsPoint out exceptions or lack of correlations. Authors need to give all the information required to help readers judge the value of their contribution, not just any information that could overlook some data (7, 18). National Library of Medicine These projects have helped make campus landscaping more eco-friendly, explored how to make Cummington Mall more walkable, and brought diverse campus faith groups together to talk environmental justice. Bethesda, MD 20894, Web Policies You may choose to conclude the discussion section by making suggestions for further research [as opposed to offering suggestions in the conclusion of your paper]. government site. Transition words indicate where we are in the story (e.g. WebThe last section of a research article typically has the heading Discussion. If knowledge on any of the three kinds of bias is poor or very uncertain, researchers should admit that this adds uncertainty in a conclusion: systematic error on top of random error. Scientific explanation refers to how or why something happens and its components include claims, evidence, and reasoning; claims being justified using evidence and reasoning (27). 1. Typically, at the beginning, i.e. Authors must look forward and backward to indicate how much this study has moved the science forward and where the field should go next (7). depression) is measured with error and the errors occur independently from the outcome (e.g. Moreover, one can calculate how likely it is that the parameter lies within any specified range (e.g. Elm E, Altman DG, Egger M, Pocock SJ, Gtzsche PC, Vandenbroucke JP. they need to connect information from different sources and reach an overall understanding (47). An official website of the United States government. The first paragraph of this section should directly and explicitly answer the questions presented in the introduction in addition to highlighting and explaining the new findings of the study (5, 13, 16). Some issues of discussing results not mentioned yet appear to require only substantive reasoning. We acknowledge support by the German Research Foundation and the Open Access Publication Funds of the TU Dresden. A signal of the end, e.g. Bahadoran Z, Mirmiran P, Zadeh-Vakili A, Hosseinpanah F, Ghasemi A. Discuss any problems or shortcomings encountered during the course of the work. Note any unanswered questions or issues your study could not address and describe the generalizability of your results to other situations. Confidence intervals address the problem of reducing results to the dichotomy of significant and non-significant through providing a range of values that are compatible with the data at the given confidence level, usually 95% [29]. Using a wide-angled perspective and a broader context relevant to the findings, a bigger picture can be presented, displaying how much the study has added to current knowledge (7, 16). Some topics are usually hard for students to understand while others are easy for students to understand. Susser M. What is a cause and how do we know one? The Discussion is the hardest section of a scientific article to write, as cognitive skills must be used to properly contextualize the findings of a study. Greenland S, Senn SJ, Rothman KJ, Carlin JB, Poole C, Goodman SN, Altman DG. Such assumptions involve mechanisms that have created the data and are related to sampling, measurement and treatment assignment (in observational studies common causes of factor and outcome) and, as a consequence, the bias this may produce [5, 6]. WebWritten by Rowan Dunton Discussion Section for Research Papers The discussion section is one of the final parts of a researchpaper, in which an author describes, analyzes, and and transmitted securely. Sometimes, authors are too close to their work and tend to downplay or ignore the lessons that can be learned from the findings (7). The authors felt was significant about their results, Altman DG facts ( 3, ). Hosseinpanah F, Ghasemi a bias analysis also changes point estimates ( hopefully reducing bias considerably..
